In the last years several mobile learning courses have been experimented. The increasing popularity and additional features of mobile devices is one of the key reasons for that development. Some of the courses are adaptations and others are fully developed for mobile devices. The superior portability and accessibility of those equipments makes them suitable for interactive learning courses. This paper...
Asymmetric stereoscopic coding can save bitrate and maintain the overall visual quality of stereoscopic perception, so it is an alternative for wireless environment in which the bandwidth is limited. In asymmetric stereoscopic coding, the right-view images are down-sampled to half resolution before coding, while the direction of sampling influences the rate-distortion performance of the asymmetric...
There is an emerging focus on real-time data stream analysis on mobile devices. A wide range of data stream processing applications are targeted to run on mobile handheld devices with limited computational capabilities such as patient monitoring, driver monitoring, providing real-time analysis and visualization for emergency and disaster management, real-time optimization for courier pick-up and delivery...
Mobile devices are carried by people, which are characterized by their need to socialize. The social character of mobile networks may have an influence in modeling the mobility of their nodes, and consequently in the performance evaluation of the network. In this paper, we introduce social behaviors into existing mobility models so as to mimic real motion of users and evaluate their impact on network...
Cell phone battery life has been a fundamental design consideration ever since the first mobile devices were introduced in the 1970's. When mobile services were restricted to voice, the problem from a system design perspective often boiled down to finding best of breed components (e.g. amplifiers, signal processors, etc.) that optimized power while not sacrificing size. However, today's cell phones...
A ubiquitous network environment is a system where the user can access network services anytime, anywhere. Studies are continuously being conducted on wireless communication technology and mobile devices to establish such an environment. The company that provides such services, at a charge to users, should have an established system for authentication and authorization. This service is referred to...
One of the major objectives of Advanced Traffic Management Systems (ATMS) is to reduce traffic congestion in urban environments by improving the efficiency of utilization of existing infrastructures. Many creative and efficient technologies have been developed over the years. Although, commuters especially drivers take a critical part in containing traffic congestion problems, they are playing a passive...
This paper presents a sequential image stitching approach for creating high-quality panoramic images on mobile devices. In this approach, each source image in the image sequence is stitched onto the panoramic image sequentially using two operations: optimal seam finding and transition smoothing. In the seam finding process, graph cut optimization finds an optimal seam and creates labeling in the overlapping...
There is a growing interest for providing interactive graphics also on mobile devices like PDAs, Smartphones, etc. Right now mobile devices are very limited concerning graphical resources basically only simple 2D rasterization operations are available, that run completely on the main CPU of the device. The desire to have more complex 3D graphics on these devices often results in a remote rendering...
